FAST Viscometer

With no moving parts, the FAST system is the perfect choice for the extreme demands such as paints, inks and coatings.
Fast viscometer

The AMETEK Brookfield FAST system has a rugged design with non-moving parts. It has been designed to perform day after day under the extreme demands in printing, coating and adhesive operations - with no maintenance. Utilizing a high frequency, micro-rotational core, which is unaffected by press vibration, this worry-free system can measure and control the viscosity of your inks, coatings and adhesives from start to finish...allowing the operators to handle other press concerns.


  • Unique micro rotational sensor
  • No moving parts, no maintenance
  • Unaffected by external vibration
  • Flexible vertical or horizontal installation
  • True temperature readings to 120°C
  • Maintains correct color throughout the process
  • Compact: only 8.5 inches tall
  • Worldwide support
